Now, I did purchase a i7 3700k, ASRock Z77 Pro4, and the H100. So if you come back to me and say it's my CPU or my motherboard, I'm okay with that because my shipment should be coming within a few weeks.

SOME RESENT THINGS I DID TO MY PC THAT MAY HAVE CAUSED THIS:

- Overclocked my GPU (I reset it yesterday, still had black screens)
- Turned off the 'Cool n' Quiet' option in the BIOS (I Tried it with this on and off, and still happened)
- Added a 660Ti to my system (Had it in for a week or two, just started to happen now)
- Added 16gb Corsair Vengeance RAM

Now, sometimes it turns off for my CPU being to hot, but I can understand that because I didn't put in the CPU and it's cooler, iBuyPower did. So If it is that, I'll just wait until my i7 comes.

Lastly, none of my steam games open up. I tried to launch BF3 in origin, and it works, but not a single one of my steam games launch. It just launches, then has a black screen and messes up my resolution.

Okay well, I got the steam games to work, but now it's just the random turning off. So far, it looks like it's when my CPU gets too hot. So will it be fixed if I add a new coat of thermalpaste to my cooler?

Computers throttle when the CPU gets too hot. That makes stuff run slower, but they don't turn off unless something's really wrong. Try one of the CPU stress tests here:Overclocking tools of the trade
- Prime95 is probably the less stressful of them, while OCCT and LinX have generated some higher temperatures for me

Anyway I concur with ZZLEE to run a GPU stress test and see what happens.

core temp should tell you what your cpu cores are running at .. i think consensus is add +10*C to what you see as there is a glitch with amd probes in it that might be old info i haven't played with amd in a bit.
